If you get this error, it is often because you have configured Apache with modules that weren't actually installed. Eg. you try to load the PHPmodule but didn't actually install the apache2 php module, so the server can't start.

How To Do Linux Network Bonding Teaming in Mint Debian Ubuntu

Bonding is an excellent way to get both increased redundancy and throughput. It is similar to the "Network Teaming" feature in Windows. There are a few different modes but we will use mode 6, I think it's the best of both worlds, as it is not just a failover, but it provides round robin, so you will get redundancy and load balancing. So if you have a 1G single port, you will have a combined throughput of 4G at this point. Just bear in mind that the true thr........

phpBB3 slow and internal dummy connection

Using Apache 2.2 and PHP5.6 PHPBB3 is very slow to respond. Actually for some reason it takes so long to even register a log entry in access_log as in several seconds or a few minutes later it shows up in Apache. All other vhosts and Apache access stops working and freezes until the request to access PHPBB3 slowly completes. It seems to randomly be slow if you stop using it whether for posting or reading the forums. I've migrated to different machines including........

mysql_real_escape_string returns an empty string solution

MySQL PHP adding a backslash/escaping apostrophes Solution

The first thing to diagnose is what is actually in the database (use PHPMyAdmin or CLI). You will of course either find that the backslash is either in the database or not. If the backslash is in the database you probably have magic quotes gpc/runtime on and/or are calling the "addslashes()" function which does this. If you are escaping your data with mysql_real_escape_string() then think again, you probably have magic quotes gpc enabled either in php.ini or........

phpBB create new email hash manually when modifying or adding user manually directly through MySQL

Many may ask why would you need to do this? When upgrading from phpBB 2 to 3 the conversion does not keep the admin user you create. If your old admin user has an email address associated that no longer works or is accessible this makes it impossible to reset the admin password. Some may just say "I'll just manually edit the e-mail address" but it won't work and phpBB will fail to find that user if you don't update the "user_email_hash" field but how do........

md: data-check of RAID array md3

This really made me nervous but notice the mdstat says "check". This is because in Ubuntu there is a scheduled mdadm cronscript that runs everyday on Sunday at 00:57 that checks your entire array. This is a good way because it prevents gradual but unnoticed data corruption which Inever thought of. As long as the check completes properly you have peace of mind knowing that your data integretiy is assured and that your hard drives are functioning properly (I'........

Ubuntu Linux HTML Rendering left bracket < problem appears as 003C box

Shutdown/Power/Halt In Debian/Ubuntu/Centos Guide Systems Doesn't Work

Different distributions such as Debian and Centos behave differently when trying to shutdown your system. shutdown -H now on Debian does not do what you'd expect. The system won't power down, it will halt and do everything but power down. shutdown -PH now will do the job though (actually power the system off). This is important to test especially if you are not near the system. If you just use -P it forcefully shuts off which is not........

Realtek r8169 1gbit/1000mbit NIC/Ethernet Goes Down/Halts on Large File Transfer/Heavy Network Usage

MySQL Insert Statement ONLY IF a duplicate entry does not exist

This is a great way to reduce MySQL code/mistakes/annoyance when doing things, take for example this statement: INSERT IGNORE INTO sometable(CatName) VALUES("someitem"); Notice the "IGNORE", that is what does the magic. Normally if the entry "someitem" existed you'd get an error message back such as "Duplicate entry for whatever".

Ihave no idea how to get the loopback device working in OpenVZ, but what's more frustrating is that I purchased a CPanel license for my VPS and clearly it is not "VPS Optimized". Although everything does seem to work at this point despite that error. The suggestions here: http://forum.openvz.org/index.php?t=msg&goto=1339 don't seem to work at all. This is an OpenVZ issue, but also a CPanel isue, why on earth would loopback support be expected in a VPS a........

Idon't think this Linksys WRT54G's strength is the wireless, it seems to have poor signal quality and transfer rates all around.

The results are still not flattering and are nothing close to native performance.
